Project fear ..! Put it away, the EC won’t let their economy tank.
The only non-fact in there is "chickens come home to roost."
So how does the EU stop those chickens coming home to roost? That's covered in the very next paragraph ----- but you labelled it Project Fear rather than see both sides of the post. You're right, the EU not so much won't let it happen, they can't let it happen.
But taking it a little further, who pays for the next round of EU QE? The EU(ECB), pretty much like every other 'country,' borrows money on the global money markets. But who services that debt? Where does the EU get their money from to service the debt? Greece? Spain? Italy?
